Application filed January 10, 1919. Serial No. 270,520.

To all whom it may concern Be it known that I, FREDERICK W. KRA sE, a citizen of'the United States, residing at North Bend, in the county of Coos and State of Oregon, have invented new and useful Improvements in Hair-Clippers, of which the following is a specification.

This invention relates to a novel construction of clippers for clipping hair and the like, and the principal object of the invention is to so form the comb plate that the device 'will cut the hair to different lengths when held in a certain position.

With the above and other objects in view the invention resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings Figure l is a front view of the device.

2 is a bottom view of the comb plate.

Fig. 3 is a central section on line 33 of Fig. 2.

Fig. 4 is a section on line 44 of Fig. 2.

Fig. 5 is a section'on line 5-5 of Fig. 2.

In these views 1 indicates the comb plate having its bottom face corrugated as at 2 andits front edge provided with the teeth- 3. 4 is the cutting plate sliding on the comb plate and provided with the cutting teeth 5. 6 indicates the handle connected with the cutting blade and comb plate, as usual. This construction of the device is well known and forms no part of my invention. My invention relates to the formation of the teeth of the comb plate, whereby the device Will cut the hair to different lengths. In carrying out my invention I bevel the front edge of the bottom of the plate as at 7 this bevel extending from the lower surface of the teeth to the front edge thereof. The bevel is inclined in both directions beginning at the center tooth and extending upwardly to each side. In this way the center tooth is of the greatest thickness while the teeth on each side gradually decrease in thickness toward the sides of the plate. It will also be seen that the center tooth is longer than the other tooth and said other tooth on each side of the center tooth gradually decreases in length toward the sides.

I prefer to form this bevel by grinding OK the front edge of the plate, which forms the bottom of the tooth, from the center, each way to the sides. This will leave the center more pointed and thicker than the sides. It will be seen that the teeth at the center are thicker than those at the sides so that these central teeth will leave the hair longer than the other teeth. It will thus be seen that the one pair of clippers may be used for cutting the hair instead of the two orthree'clippers of difierent sizes, as now used. The ridge left by the clippers is blended out by using scissors or shears. By holding the clippers at a perfect angle they will cut the hair to. the same length.

What I claim is 2-- 1. A clipper of the class described, comprising a comb plate, having the lower edge of its tooth part cut away at an angle beginning at the center and extending upwardly to each side.

2. A clipper of the class described, comprising a comb plate, having its front edge beveled, said bevel extending from the lower surface of the teeth to the front edge thereof and said bevel inclining upwardly from a point beginning at the central tooth toward each side of the plate.

In testimony whereof I aflix my signature. I

FREDERICK W. KRAUESF.
